Analysis should include
- defining the terms alternating current, time period, frequency, and amplitude
- identifying potential safety hazards when working with alternating current
- measuring AC voltage using digital multimeters and oscilloscopes
- measuring frequency and amplitude of an AC signal using an oscilloscope and signal generator
- calculating instantaneous and average values and effective (RMS) voltage or current
- converting RMS, peak, and peak-to-peak AC voltage values
- calculating frequency and time period of an AC waveform.
Process/Skill Questions:
- What is the relationship of time period to frequency in an AC circuit?
- Why is it important for a technician to know how to use an oscilloscope?
- What is the frequency of the AC voltage provided from a wall outlet?
